Hip and Shoulder Range of Motion in Youth Baseball Pitchers

This is a preliminary study to investigate the feasibility of electronic moxibustion in breast cancer patients with upper limb lymphedema. As current treatment options for lymphedema are unsatisfactory and time consuming, there have been attempts to manage symptoms using integrative treatments. Electronic moxibustion was developed to compensate for the shortcomings of conventional moxibustion and is widely used in clinical practice. However, there have been no studies on using electronic moxibustion in breast cancer-related lymphedema. To investigate the feasibility of electronic moxibustion in treating breast cancer-related lymphedema, this study included subjects who completed primary cancer treatment at least 6 months ago and had more than 10 mm difference in arm circumference of upper limbs. All subjects were assigned to the treatment group. Subjects were treated with 16 sessions (30 minutes/session) of electronic moxibustion for 8 weeks followed by 4 weeks of follow-up. For outcome measures, upper limb circumferences, shoulder range of motion, bioimpedance analysis, and quality of life questionnaire were assessed. All 10 subjects completed the study. The effective index showed 38.21% reduction after treatment ( P = .0098) and 29.35% ( P = .0039) after 4 weeks of follow-up compared to the baseline. The reduction of lymphedema was most prominent at 10 cm above the elbow crease, where the mean reduction of circumference difference was 7.5 mm ( P = .0430) and continued to improve after treatment (mean reduction of 8.3 mm, P = .0156). There was significant improvement in shoulder range of motion only in flexion and internal rotation at week 9. There were 7 adverse events, and most were irrelevant to the treatment. Only 1 participant had a mild burn on the acupuncture point. Here, we demonstrate for the first time that electronic moxibustion treatment is a feasible treatment for breast cancer-related lymphedema. Electronic moxibustion may reduce differences in upper limb circumference and improve shoulder range of motion. A future comparative clinical trial is needed to confirm the clinical efficacy of this treatment.

BACKGROUND: Persisting shoulder stiffness adversely affects quality of life by causing pain and motion restrictions especially in patients with diabetes. OBJECTIVE: The aim of this study was to evaluate the outcomes of arthroscopic capsular release in patients with idiopathic shoulder stiffness. METHOD: A literature search was conducted in electronic databases and studies were selected by following precise eligibility criteria. Random-effects meta-analyses were performed to estimate the changes at latest follow-up in scores of the Constant, American Shoulder and Elbow Surgeons (ASES), and University of California at Los Angelis (UCLA) scales, Visual Analogue Scale (VAS), and shoulder range of motion. RESULTS: Nineteen studies were included. The follow-up duration was 42 months [95% confidence interval (CI): 32, 51]. Improvements in scores of the Constant, ASES, UCLA scales, and VAS were 48.3 [95% CI: 38.0, 58.6], 44.6 [95% CI: 24.6, 64.6], 19.3 [95% CI: 16.6, 22.0], and -6.1 [95% CI: -6.9, -5.4] respectively (P< 0.05 all). Improvements in the shoulder range of motion were: abduction 82.0 [95% CI: 65.0, 98.9]; forward flexion 75.9 [95% CI: 59.7, 92.1]; external rotation 43.2 [95% CI: 37.5, 49.0]; and internal rotation 25.4 [95% CI: 15.2, 35.5] degrees; P< 0.05 all). CONCLUSION: Arthroscopic capsular release effectively improves shoulder function in patients with idiopathic shoulder stiffness.

AbstractCurrently it is hypothesized that increased body mass index may contribute to overuse injuries. Thus, if hip or shoulder range of motion is affected by body mass index, pitchers may be placing additional stress on joints as they seek to pitch at maximal velocity. The purpose of this study was to examine if range of motion at the hips and shoulders were related to body mass index classification. A sample of 147 female softball pitchers (17.0±4.2 years; 167.6±11.8 cm; 70.6±17.5 kg; body mass index=24.8±4.7 kg/m2) participated. Bilateral hip and shoulder range of motion were assessed. Multivariate analysis of variance results indicated body mass index [Wilks’ Λ=0.742, F=1.722, p=0.014, η2=0.095] significantly affected range of motion of the shoulder and hip. Post hoc results indicated the underweight group had significantly more range of motion than the obese group in hip internal range of motion on both the throwing side (mean difference=12.39, p=0.005) and glove side (mean difference=11.98, p=0.004). Although body composition is not overly emphasized among softball pitchers, the current study reveals excess weight may inhibit proper mechanics. Coaches, athletic trainers, strength and conditioning personnel, and athletes should acknowledge the role that body composition can play in affecting pitch outcomes.

Background: Reducing the number of pitches thrown is regarded as the most effective way to prevent throwing injuries in youth baseball pitchers. However, few studies have compared the effectiveness of limiting the pitch count versus the limiting the number of innings pitched in terms of elbow injuries. Hypothesis: We hypothesized that, compared with inning limits, pitch count limits would lead to greater decreases in elbow pain, range of motion deficits, positive moving valgus stress test results, and the risk of capitellar osteochondritis dissecans (OCD). Study Design: Cohort study; Level of evidence, 3. Methods: This study retrospectively reviewed baseball pitchers aged 8 to 12 years in 2017 and 2018. Inning and pitch count limits in games were set to a daily maximum of 7 innings in 2017 and 70 pitches in 2018. Elbow pain, range of motion, and moving valgus stress test results were evaluated. The presence of capitellar OCD was assessed on ultrasonographic and radiographic images. Results: A total of 352 pitchers in 2017 and 367 pitchers in 2018 participated. The mean pitch count per game was lower in the pitch count limit (CL) group (52.5 ± 16.0) than in the inning limit (IL) group (98.2 ± 19.5) ( P < .001). Compared with the IL group, the CL group had significantly lower rates of elbow pain (40.9% vs 31.9%, respectively; P = .01) and reduced flexion (19.0% vs 10.6%, respectively; P = .001). Multivariate analysis revealed a significant association between elbow pain and age in both the IL and the CL groups ( P < .0001 and P = .02, respectively) and between OCD and elbow pain in the CL group ( P = .04). Conclusion: A pitch count limit of ≤70 pitches per day for baseball pitchers ≤12 years could be more protective against elbow pain and reduced flexion than a limit of ≤7 innings per day, but it may not be effective for reducing the risk of capitellar OCD.
